I am planning to replace my mobile phone with a simple/basic/dumb/feature mobile phone (which is not smartphone) for my main calling purpose sim. My main concern is I get lots of spam calls. So I want a mobile phone which has inbuilt call blocking feature. In Smartphone we can install app for this purpose, but feature phones we cant install app. So I would like to know if there are any feature phones in price range of 2K~4K which has inbuilt call blocking feature. I had seen 1 Karbonn brand handset which had this feature. But I would prefer Nokia/Samsung brand phone with this feature.
